Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Differentiate and validate
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

App Store description
PepTrack is the all-in-one companion for anyone on a peptide protocol. Whether you're taking semaglutide, tirzepatide, or other peptides, PepTrack helps you stay on top of your doses, monitor hunger patterns, and make informed decisions with your healthcare provider. **Track Your Hunger** Log how hungry you feel throughout the day on a simple 1-5 scale. Set up smart reminders so you never forget to check in. Over time, see exactly how your appetite changes in response to your protocol. **Log Every Injection** Record each dose with the date, amount, and medication. Keep a complete history of your peptide journey in one place. **See Your Progress** Visualize your data with beautiful charts and a color-coded calendar heatmap. Spot trends, compare hunger levels against injection dates, and watch your progress unfold over weeks and months. **Built-In Peptide Tools** - Dose Calculator: Enter your vial size, water amount, and desired dose — instantly see how many units to draw on your syringe, plus concentration details. - Reconstitution Calculator: Find the ideal BAC water amount for your vial to get clean, easy-to-measure unit counts. **Peptide Library** Browse built-in profiles for popular medications including Ozempic, Wegovy, Mounjaro, Zepbound, and more. Each includes dosing info and blood level tracking with half-life curves. **Smart Insights** Get data-driven suggestions on whether your current dose is working, based on your hunger trends and injection history. Always designed to support — never replace — conversations with your doctor. **Your Data Stays Yours** All data is stored locally on your device. No accounts, no cloud uploads, no third-party tracking. Export anytime as CSV or JSON.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

BUILD KIT DIFFICULTY
Intermediate
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
